Restriction of sexual reproduction in the moss along an elevational gradient.
Ecol Evol
September 2020
Terrestrial plant populations located at the margins of species' distributions often display reduced sexual reproduction and an increased reliance on asexual reproduction. One hypothesis to explain this phenomenon is that the decline is associated with environmental effects on the energetic costs to produce reproductive organs.In order to clarify the changing processes of sexual reproduction along an elevational gradient, we investigated the sexual reproductive parameters, such as the number of sporophytes and gametangia, in , a dioicous moss found on Mt.

- All photosynthetic organisms experience photoinhibition, which can be detrimental in extreme environments, making it crucial to analyze how varying light conditions affect their ecological behaviors.
- The study assessed how different wavelengths of light affect the photoinactivation of photosystem II in three species from East Antarctica, using advanced spectrograph techniques.
- Findings showed significant differences in photoinactivation responses: lichen was the most resistant across all wavelengths, while the bryophyte was particularly sensitive to UV-B, and the green alga demonstrated higher sensitivity to UV-A, highlighting that P. crispa has to expend more energy to recover from light damage than the other two species.
